One tempo for the whole page — the metronome, the drums below and the chord player all follow this BPM, live, even mid-song.

Play All plays the selected style and the chord progression together — and stays on that style, no rotation. Starts and stops land on the downbeat, so the beat and the chords never drift apart.

Tap a style to play it — tap the playing style again to step through Simple, Groovy and Full.

Progression

Chord names — Am, F#7, Bbmaj7, G/B — or Roman numerals in the key above — I, V, vi, ii7. Tap any chord chip to hear it on its own. Hit Play while the beat is running and the chords join on the next downbeat. Pick a new progression — a preset, a new key, or typing — while it's playing and the new chords swap in on the next downbeat; playback keeps going.

Touch sets how busy each player gets: the drums step through their Simple, Groovy and Full patterns, the bass goes from holding the root to pumping quarters to a walking line, and the chords from one pad per chord to a strum every beat to arpeggios.

Tap a string to hear its pitch — or listen with the mic and tune to the needle.
